I will try and help with this problem with your Siemens IQ300 Dishwasher
The first thing you need to do is make sure that the rotating arm has not got blocked Jets, or maybe you have a weak pump. I am not really able to help you further as you have not included your full model number this can be found on the inside of the door normally engraved into the stainless steel
If you need any further assistance please feel free to contact me. all the best Paul.
